Sansevieria plant named ‘Lauren’

ABSTRACT

The new variety Lauren is part of the “long leaves  Sansevieria ” varieties. It can reach 85 cm in length, with an average of approximately 11-13 leaves per plant. The plant is cylindrically shaped, the arrangement of the leaves is in the form of a rosette. Shows colors very different from its parent variety (‘Jaboa’, unpatented) Unlike its parent variety it shows variegated leaves (different green tones on the irregular bands) and light greenish colored stripes along the margins, but ‘Jaboa’ presents less leaves per rosette.

Latin name of the genus and species of the claimed plant: Sansevieria trifasciata.

Variety denomination: ‘Lauren’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sansevieria plant, botanically known as Sansevieria trifasciata, of the family Ruscaceae hereinafter referred to by the cultivar name ‘Lauren’.

Sansevieria is a monocotyledonous and succulent plant which can be produced in either hard-leafed or soft-leafed varieties for interior use as a house plant or outdoors.

The new variety ‘Lauren’ originated as a naturally-occurring mutation of the Sansevieria trifasciata ‘Jaboa’ (unpatented). The new Sanseviera ‘Lauren’ was discovered and selected by the inventor Marvin Gonzalez Villegas, as a single sprouting rare mutated plant in a plantation containing plants of Sansevieria ‘Jaboa’, a controlled environment, in 2015 in Monterrey, San Carlos, Alajuela province, Costa Rica.

Asexual reproduction of the new Sansevieria cultivar ‘Lauren’ by vegetative cuttings was first performed in 2015 in Monterrey, San Carlos, Alajuela province, Costa Rica, and demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Lauren’, which in combination distinguish this Sansevieria as a new and distinct cultivar:

-   -   1. Variegated foliage with different green tones on the         irregular bands, and light green colored margin bands in the         leaf blade     -   2. wide and lanceolate leaves, supported in a rosette.     -   3. 60-85 cm plant height.     -   4. Plant habit: Erect     -   5. Needs little water and is drought tolerant.

The new variety ‘Lauren’ is considered a variety of Sansevieria in the group denominated as “long leaves Sansevieria varieties”. The new variety presents an average of 11-13 leaves per plant when it reaches its maturity (between 8-12 months). The new variety has an erect growth habit and the entire plant can reach a height range between 60-85 cm. The leaves are slightly wide (6-8 cm average measured at the widest part of the mature leaf) and lanceolate, with a soft waxy texture. The blades are thin and slightly wavy. The plant has a cylindrical shape.

The new variety is moderately drought tolerant, adapts to conditions of light and shade (interior and exterior), and shows resistance to antrachnose (Colletoirichum sansvierae) disease.

The leaf blade is green colored (RHS 142A), with non-uniform vertical variegated bands in both sides of the leaves, dark green (RHS 141A) colored, non-uniform stains along both sides of the leaves, white colored, and also presents broad longitudinal light green (RHS 150A) colored stripes along the margins. The margins of the leaf are dark red colored (RHS N34A).

The variety ‘Jaboa’ gave rise to the variety ‘Lauren’. The ‘Jaboa’ is also considered part of the “long leaves varieties” group. The claimed variety shows a higher number of leaves per plant (11-13) than ‘Jaboa’, and less wide with an average width of 6-8 cm (measured in the middle of the mature leaf.) The growth habit is erect and presents narrow leaves supported in a rosette. The entire plant can reach a size between 60-85 cm. The plant has an inverted triangle shape.

Plants of the new Sansevieria ‘Lauren’ differ from plants of the parental cultivar, ‘Jaboa’ (unpatented) in the characteristics described in Table 1.

New Cultivar Parent Characteristic ‘Lauren’ ‘Jaboa’ (unpatented) Plant Vigor more vigorous less vigorous (more leaves) (less leaves) Color variegated leaves (different variegated leaves green tones on the irregular (different green bands) and light green colored tones on the stripes along the margins irregular bands) Shape wide and lanceolated wide and lanceolated leaves on a rosette leaves on a rosette Texture of smooth-textured leaves smooth-textured leaves leaves

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Sansevieria ‘Lauren’ is the Sansevieria ‘Jaboa’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘Lauren’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describe the color of ‘Lauren’.

DETAILED BOTANICAL DESCRIPTION

The new Sansevieria ‘Lauren’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar ‘Lauren’ as grown in open-field conditions at Monterrey, San Carlos, Alajuela province, Costa Rica, under conditions which closely approximate those generally used in commercial practice. 24.5° C. during the day and 18° C. at night. Plants grow under natural light conditions.

This crop does not require constant fertilization, to increase production per area about 200 kg ha−1 N, 150 kg ha−1 of P and 100 kg ha−1 K are required, the production is closely related with soil conditions in which they are grown.

Color references are made to The Royal Horticultural Society Colour Chart Online last accessed Sep. 2, 2016), except where general colors of ordinary significance are used. The photographs and descriptions were taken during the rainy season in Monterrey, San Carlos, Alajuela province, Costa Rica when outdoor day temperature was 23° C. The age of the plants described is 8 months.
